Hi, thanks for your fix! I am currently working on implementing the lz4 support for libpq compression. Looking forward to post an update soon.

Forgot to attach the updated patch :)

This fails to build on Windows due to the use of strcasecmp:

+ if (strcasecmp(supported_algorithms[zpq->compressors[i].impl], "zstd") ==

Was that meant to be pg_strcasecmp?

To keep this thread from stalling, attached is a rebased patchset with the
above mentioned fix to try and get this working on Windows.
